In modified plastics, how long is the long glass fiber 2023-03-27

1. The optimum length of glass fiber in resin matrix The length of the glass fiber in the resin matrix is too short, only play the role of filler, not to strengthen the role; Too long, although the enhancement effect is significant, but affect the dispersion of glass fiber in resin matrix, molding processing performance and product performance. Therefore, it is generally believed that the ideal le...

Typical applications of long glass fiber reinforced plastics in the automotive industry 2023-07-04

Long fibre reinforced thermoplastics (LFT) is the most commonly used base resin for LFT, followed by PP, PA and also PBT, PPS, PPA, TPU and other resins. It is worth mentioning that different fibers are needed for different resins to achieve better results. Development of LFT In 1980, Polymer Composites Corporation (PCI), USA, was the first to propose the theoretical design concept of LFT, and con...
